Description

Technical Field

[0001] This invention relates to the field of glass bottle production technology, specifically to a device for preventing diffusion when a bottle is tilted during quenching. Background Technology

[0002] During the production of glass bottles, the formed glass bottles need to be quenched. During quenching, multiple glass bottles need to be arranged inside the quenching chamber. In order to ensure that there is sufficient quenching space around the glass bottles, a certain quenching gap needs to be maintained between every two glass bottles. However, due to the limited gap between the glass bottles during quenching, if one glass bottle tipps over, a diffusion phenomenon will occur, causing a whole batch of glass bottles to tip over. It will then take a lot of time to right them. Therefore, when quenching batches of glass bottles, it is best to use a bottle-tilting anti-diffusion device to ensure that an individual glass bottle does not cause a butterfly effect after it tipps over.

[0003] For example, Chinese patent publication number "CN209739752U" discloses a "bottle anti-tipping device," whose main structure includes an upper fixing ring and a lower fixing ring. At least one connecting rod is provided between the upper and lower fixing rings. The upper fixing ring has a threaded hole with a fastening screw inside, the threaded hole pointing towards the center of the upper fixing ring. At least three adjusting arms are fixedly connected around the lower fixing ring, and the outer ends of the adjusting arms are equipped with a lifting support structure. The bottle is placed within the upper and lower fixing rings, and the fastening screw ensures a tight contact between the bottle and the upper fixing ring, maintaining stability. The adjusting arms increase the contact area between the lower fixing ring and the ground, and the lifting support structure can adapt to uneven ground or ground with a certain slope, ensuring the bottle is placed vertically and solving the problem of the bottle easily tipping over.

[0004] When the aforementioned anti-tipping device for bottles is used in the quenching chamber, in order to improve work efficiency, glass bottles are quenched in batches. Multiple devices will seriously affect the working space of the quenching chamber. In addition, since it is necessary to manually adjust each adjusting arm and fastening screw, it will seriously waste working time, resulting in low efficiency of pre-quenching preparation.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1 The anti-diffusion device for a bottle-tipping platform includes a bottom protective plate 1 and a top protective plate 2, a bottom fixing plate 3 and a top fixing plate 4 respectively disposed on the sides of the bottom protective plate 1 and the top protective plate 2 along their length, and a through hole 6 for the main rod disposed inside the top fixing plate 4. The bottom protective plate 1 is preferably close to the surface of the quenching platform. When the glass bottles placed on the surface of the quenching platform are pushed and arranged in a concentrated manner, the bottom surface of the glass bottles will slide and rub against the quenching platform. The fact that the bottom protective plate 1 is close to the surface of the quenching platform can ensure the stability of the glass bottles during movement. Therefore, when adjusting the horizontal position of the glass bottles, the top protective plate 2 needs to be in contact with the surface of the bottom protective plate 1 to increase the protection of the bottom of the glass bottle and facilitate its movement.

[0027] To achieve the horizontal limiting function for the glass bottle, please refer to [link / reference]. Figure 1 and Figure 2Multiple diamond-shaped through holes 5 need to be set, evenly distributed inside the bottom protective plate 1 and the top protective plate 2. The glass bottle can be placed on the quenching table surface through each diamond-shaped through hole 5. In order to achieve the upper and lower corresponding glass bottle limiting capability, the diamond-shaped through holes 5 in the bottom protective plate 1 need to be set in correspondence with the diamond-shaped through holes 5 in the top protective plate 2. In order to provide sufficient quenching space for the glass bottle in the diamond-shaped through hole 5, the line segment formed by the two farthest endpoints in the diamond-shaped through hole 5 needs to be collinear with the length direction of the bottom protective plate 1 and the top protective plate 2. The distance between the two nearest endpoints in the diamond-shaped through hole 5 needs to be greater than the diameter of the glass bottle placed inside it. After the glass bottle is adjusted to a horizontal position, the body of the glass bottle will not contact the bottom fixing plate 3 and the top fixing plate 4. Therefore, the body of the glass bottle has quenching space, which can effectively prevent the diffusion phenomenon caused by the tipping of a single glass bottle without contacting the glass bottle body. Thus, the glass bottle can be effectively protected while having sufficient quenching space.

[0028] To ensure stable protection of the glass bottle under various conditions, please refer to [link / reference needed]. Figure 1 , Figure 3 and Figure 4 Two buffer-type spacing adjustment structures 7 are required, which are fixedly installed on the upper surfaces of the two top fixing plates 4 respectively. Inside each structure is a piston 75 that moves longitudinally under liquid pressure and the action of a helical spring 77, thereby causing a change in the spacing between the bottom fixing plate 3 and the top fixing plate 4. When the glass bottle needs to be adjusted horizontally, the piston 75 can move to its highest point under the elastic action of the helical spring 77. Since the upper end face of the piston 75 abuts against the top end face of the longitudinal telescopic cavity 73, the upper end face of the bottom fixing plate 3 abuts against the top fixing plate 4. The lower end face of plate 4 allows the bottom fixing plate 3 and the top fixing plate 4 to overlap, thereby increasing the protection of the bottom of the glass bottle and facilitating its movement. During the quenching of the glass bottle, a hydraulic system can be used to inject liquid into the longitudinal telescopic cavity 73. Under the action of liquid pressure, the telescopic rod 76 extends downward, and the distance between the bottom fixing plate 3 and the top fixing plate 4 will increase. The specific increase in height can be set according to the requirements. Of course, the top fixing plate 4 after the increase in height needs to be able to prevent the glass bottle from tipping over, effectively preventing the diffusion phenomenon caused by the tipping of a single glass bottle.

[0029] For details regarding the specific structure of the buffered spacing adjustment structure 7, please refer to [link / reference]. Figure 3 and Figure 4The system includes a longitudinal hollow rod 71, with a first fixing plate 72 fixedly installed on the upper surface of the top fixing plate 4 at the bottom end of the longitudinal hollow rod 71. A longitudinal telescopic cavity 73 is provided inside the longitudinal hollow rod 71, and a liquid inlet pipe 74 communicating with the longitudinal telescopic cavity 73 is provided at the top end of the longitudinal hollow rod 71. A piston body 75 that can move along its axial direction is placed inside the longitudinal telescopic cavity 73 of the longitudinal hollow rod 71. In order to prevent the flow of liquid in the moving gap, a high-pressure sealing ring is required to be placed on the circumferential side of the piston body 75. A telescopic rod 76 that penetrates the bottom end face of the longitudinal hollow rod 71 and the through hole 6 of the main rod body is installed at the bottom end of the piston body 75. A coil spring 77 in a compressed state is sleeved around the rod body located inside the longitudinal telescopic cavity 73 of the telescopic rod 76. A second fixing plate 78 fixedly installed on the upper surface of the bottom fixing plate 3 is provided at the bottom end of the telescopic rod 76.

[0030] To ensure the stability of the horizontal movement of the bottom fixing plate 3 and the top fixing plate 4, please refer to... Figure 1 and Figure 5 Two anti-rotation limiting structures 8 need to be set up, which are fixedly installed below the two bottom fixing plates 3 respectively. Inside each structure, there is a main base 81 that can be fixedly installed on the quenching table surface, and a polygonal limiting rod 83 that passes through the base 81 and moves along the axial direction of the base 81. When the polygonal limiting rod 83 is subjected to radial thrust or tension, it can simultaneously drive the bottom fixing plate 3 and the top fixing plate 4 to move horizontally. Since the cross-sectional shape of the polygonal through hole 82 is consistent with the cross-sectional shape of the polygonal limiting rod 83, both being polygonal structures, and the cross-sectional dimensions of the polygonal through hole 82 match the cross-sectional dimensions of the polygonal limiting rod 83, the bottom fixing plate 3 and the top fixing plate 4 will only move horizontally and will not cause the bottom fixing plate 3 and the top fixing plate 4 to flip over, thereby achieving the stability of the horizontal movement of the bottom fixing plate 3 and the top fixing plate 4.

[0031] For details regarding the anti-rotation limiting structure 8, please refer to [link / reference]. Figure 5 It includes a main base 81 that can be fixedly installed on the quenching table surface. The main base 81 has a polygonal through hole 82 in its axial direction. A polygonal limiting rod 83 is inserted into the polygonal through hole 82. One end of the polygonal limiting rod 83 is fitted with a vertical plate 84 that is fixedly installed on the bottom surface of the bottom fixing plate 3. The other end of the polygonal limiting rod 83 is fitted with a limiting fixing plate 85.

[0032] To achieve the ability to adjust the space of the glass bottle, please refer to [link / reference]. Figure 1 and Figure 6A threaded horizontal adjustment structure 9 needs to be installed at the horizontal end of one of the polygonal limiting rods 83. Inside the structure is a sub-base 91 that can be fixedly installed on the quenching table surface, and a threaded rod 93 that is installed inside the sub-base 91 via a threaded structure and can drive the bottom fixing plate 3 to move directionally during rotation. Since the threaded structure includes an internal thread structure in the internal thread hole 92 and an external thread structure on the rod body of the threaded rod 93, and the internal and external thread structures are matched, when the threaded rod 93 is rotated directionally, it can simultaneously... The bottom fixing plate 3 and the top fixing plate 4 move horizontally. Due to the shape of the diamond-shaped through hole 5, after the diamond-shaped through hole 5 comes into contact with the glass bottle body, it continues to move, causing the glass bottle body to move autonomously to the symmetrical center line of the diamond-shaped through hole 5. When all the glass bottle bodies have moved to the symmetrical center line of their respective diamond-shaped through holes 5, the threaded rod 93 is rotated in the opposite direction, so that each glass bottle body is located at the center of its respective diamond-shaped through hole 5, thereby realizing the ability to adjust the space of the glass bottle.

[0033] For details regarding the specific structure of the threaded horizontal adjustment structure 9, please refer to [link / reference needed]. Figure 6 The system includes a sub-base 91 that can be fixedly installed on the quenching table surface. The sub-base 91 has an internally threaded hole 92 in its axial direction. A threaded rod 93 is installed in the internally threaded hole 92 via a threaded structure. A hand crank 96 is installed at one end of the threaded rod 93. An axial protrusion structure 94 is provided at the other end of the threaded rod 93. The end shaft of the axial protrusion structure 94 is installed in the shaft hole of a bushing 95 via a bearing. One end of the bushing 95 is fixedly connected to the end face of one of the limiting fixing plates 85.

[0034] In use, the bottoms of the secondary base 91 and the main base 81 are fixedly installed in the working position, and the bottom fixing plate 3 and the top fixing plate 4 need to be located inside the quenching chamber of the quenching equipment. Then, the glass bottle is passed through each of the diamond-shaped through holes 5, and the bottom of the glass bottle is placed on the table of the quenching table. Then, the hand crank 96 is turned so that each glass bottle is located in the center of each of the diamond-shaped through holes 5, and the glass bottle can be quenched. When a single glass bottle is tilted, the top fixing plate 4 located above can effectively isolate it and prevent it from touching the surrounding glass bottles, thereby preventing the spread of the phenomenon.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
